Mission Impossible: The Fountain

In the episode The Fountain the team try to convince their target that they have found the fountain of youth requiring Casey (Linda Day George) to perform a complex double mask trick.

In a borrowing from She and Lost Horizon the apparently youthful Casey suddenly ages rapidly, collapses and dies. To achieve this effect Casey supposedly wears a mask of her own face on top of another mask with a withered, ancient appearance: she also dons two pairs of latex gloves. At the critical moment she collapses, dissolves the top mask and gloves with solvent, greys her hair and injects herself with a drug to simulate death: all in front of the target.
